FIRE EXTINGUISHING- DEVICE.

' APPLICATION 11.21) MAILZB, 1905. A

ATTORNEY draws the lever' 27 down to the position shown in dotted lines, Fig. 2. The end 28 of the lever 27 extending in the casing forces the j casing secured to and projecting from the bottom of said tank, a valve mounted on a Valve above the valve-seat. The valve now being open the Water Will escape through the opening in the end of the casing to the roof and Wi i be on the roof and preventing the roof from catching fire from any adjoining building.

Having thus described my invention, I claim 1. In a fire-extinguishing device, comprising a casing, a valve-seat extending downgiardly from the top into said casin a valve mounted on a valve-stern, and adapted to register with the val "e-seat on the top of the imn'iediately spread over the whole roof, thereby extinguishing any lire that may i casing; spiders fixed to said va1ve-stem for guiding the valve-stem in. its movements, a I

projection fixed to one of the spiders and extending downward in said casing, a lever operatively attached tosaid projection, a graduated scale of notches on the outer end of the lever for en aging a wei ht and a turnbuckle connection or holding t e lever to the meals for operating same.

2. The combination. with a casing a valve mounted on a movable valve-stem therein, an arm for lifting the valve-stem, said arm being mounted on the side of said casing and the end of the arm extending into the casing,

adapted to engage with rollers mounted on a P10]G(Jti0ll attached to the valve-stem, and a fusible joint connecting the arm with a lookpin in a yoke attached to a washer on the under side oi the tank, and means for manually withdrawing the lock-pin from the yoke,

l l l i thereby releasing the valve-operating mechanism.

3. The combination with a Water-tank, a

drawing the look-pin from the yoke thereby releasing the valve-operating mechanism.

i. The combination with a water-tank, a casing secured to the bottom of said tank, a valve mounted on an actuating valveste1n in said casing, a lever for lifting the valve-stem, said lever being mounted on the side of the casing, one end of the lever extending into the casing, said end being adapted to engage with rollers mounted on a projection attached ti the valve-stem, a thermally-controlled oint connecting the lever with a locking means in a yoke attached to a Washer on the bottom of the tank, and means for manually withdrawin the locking means from the yoke thereby releasing the valve-operating mechanism.
